Exponent
Sign 31
Mantissa 30
Operations are perfomred with an implied binary point between bits 31 and 30. When the implied most significant nonsign bit is made explicit, it is located to the immediate ledft of the binary point. the floating-point number x is given by the following:
x = 01.f  23 if s = 0
x = 10.f  23 if s = 1
x = 0 if e = -128

4. You must use the following reserved values to represent 0 in the extended-precision floating-point format:
e = -128
s = 0
f = 0
That is, the floating point representation of 0 is:
0 = h
while the floating point representation of 1 is:
1 = h

6. Don’t forget 2’s complement
